Ww2 vehicle stowage boxes

[Ray Mulder]

Can anyone identify these metal boxes.
They are from an regional city in Queensland Australia where there were up to 60 000 US Troops Stationed during the Pacific campain. A camp site existed about 8 klm from my property and I believe an artillery unit was stationed there, I was told some equipment was recovered many years ago including a damaged Boyes.

Under the white paint is standard WW2 army green. they have captured nuts on some mounting holes and the doors are hindged piano type. While I say Top, Rear etc they could have been mounted in any orientation, the divider has about a 1/3 round fold to provide strength so I assume the way it is standing is top or bottom
You can still see the 3 mounting frame positions across them and that side is flanged. It looks as though the mounting could be like a folded fuel tank mount type.
